非对易超对称Chern-Simons物质模型

Noncommutative supersymmetric Chern-Simons-matter model

A. C. Lehum

摘要:

利用超场形式,在正则非对易条件下,计算了三维非对易超对称Chern-Simons物质模型中的Kahlerian有效超势. Kahlerian有效超势的计算足以确定该模型是否可以表现出自发(超)对称性破缺。结果表明,该模型具有自发的规范对称性破缺相,产生质量的标量和规范超场在两圈的顺序。就像对易的版本一样,在非对易的情况下,超对称性不能通过科尔曼-温伯格机制的辐射修正而被打破。

英文摘要:

Using the superfield formalism and implementing the canonical noncommutativity, the Kahlerian effective superpotential is evaluated in the three-dimensional noncommutative supersymmetric Chern--Simons-matter model at the two-loop order. The computation of the Kahlerian effective superpotential is enough to determine whether the model can exhibit spontaneous (super) symmetry breaking. It is shown that the model possesses a spontaneous gauge symmetry broken phase, generating masses for the scalar and gauge superfields at the two-loop order. Just as for the commutative version, in the noncommutative case the supersymmetry cannot be broken by radiative corrections via the Coleman-Weinberg mechanism.
